Started putting the new Fresh Air Exhaust. Still needs some adjustment. Not quite finished. Put everything on and I think I need a little longer exhaust hose. FAE is sending it out today. Here are some pictures of how far I have gotten.

I got lucky and was able to use a couple of screws from my swim platform to hold the bar. Once I get the new hose I will be able to cut and mount the two poles.

you still have the fun job ahead of you drilling the holes for the screw/bolt thru the stainless steel pipe ... I hated that one - especially as I cut the pipe in the first round too long and had to do it twice ...

What are the advantages of using a Fresh Air Exhaust on an engine that is already CAT'd and has ultra low emissions, like the 343? Were you trying to reduce the noise?

Both reducing the noise (#1 reason) and also getting rid of vapors (#2 - when it was cold this winter, you could see the vapors rolling back into the boat - made my hypochondriac wife say she started feeling ill. She never had a problem before, only once she could see it).
